Here's a screenshot with the Score system enabled. Notice that:
1. Scores have been calculated, even though I don't use them (this is
fine, maybe over the long term they'll become accurate and I'll start
using them)
2. The order of the Favourite Tracks (which is the same in both
screenshots) is determined by score
